Setting aside your skepticism for a moment, make a list of ten actions you could take, right now, that you suspect might make you feel more prosperous-- and that cost nothing.
Example:
1. Taking a walk in nature
2. Going for a run and taking a long, hot shower afterward
3. Cooking soup using leftovers I have in the house
4. Cleaning-- really cleaning-- the bathroom, and lighting the candle that I've always "saved" for special occasions
5. Calling my friend Laura in Chicago
Etc.
There are many actions we can take every day that will give us a sense of true prosperity. Choose one action from your list and notice how you feel after you have done it.
